Porównanie wpływu zachmurzenia na warunki lotów dla lotnictwa treningowego i ratunkowego w zachodniej i wschodniej części Karpat Polskich (?na przykładzie Bielska-Białej i Leska?)

Comparison of influence of cloudiness on flight atmospheric conditions for training and life-saving aviation in western and eastern part of the Polish Carpathian Mts. - example of Bielsko-Biała and Lesko synoptic stations

Summary: The author's aim was to compare of cloudiness elements influencing on flight atmospheric conditions in western and eastern part of the Polish Carpathian Mts. On described area training and life-saving aviation has special role. There are clouds with low base and the stormy ones. The observational data (?1971?-?2000?), from three main terms, collected by synoptic stations of the Institute of Meteorology and Water Management National Research Institute in Bielsko-Biała and at Lesko were used. Annual and multiannual values of low- and midlevel cloudiness, as well as frequency of cloud genera with low base were considered. Fluctuations of cloudiness value in the range of 50?-?55?% was observed in Bielska-Biała and that of 55?-?65?% (?exceptionally over 70?%?) at Lesko. In the first case decreasing trend of cloudiness was found (?fig. 1?). In Bielsko-Biała Stratus (?about 10?%?) prevailed a little and at Lesko Cumulonimbus (?about 20?%?) distinctly dominated (?fig. 2?). In both discussed parts of the Polish Carpathian Mts. frequency of the first cloud type in analysed period has decreased (?fig. 3?) while the second one has increased (?fig. 4?). Better conditions of flights with tendency to improvement, were stated in Bielsko-Biała while worse and worsening ones at Lesko. However, this study is only an introduction to explaining the stated difference causes.
